Hello, It has been some years ago when I worked with flex.
I just started with flex 4.6 for mobile. I did some testing but could not really undertand the spark
For example if you have a spark label and apply some text to it, you don't know the new label height as
I traced out it's alway 0. Only when it's added to the stage you can trace it's height.
All components seem to work differently with setting the width and height as I was used to Flex.
Does this mean I have to add all elements
I need first to the stage and then when loading external text reposition everything? I tried that, but then you see
the first time a split second a strange layout and then it gets resized and repositioned.
Does anyone have short description on how it supposed to work?
I'm not sure if I've understood your question right - but, you may want to check out this Help topic: Use text in a mobile application, and see if it helps.
In general, to get started with mobile application development using Flex 4.6, see:
Hope this helps,
